maitiro

Kugadzirwa kweAroid app kunoda kushandiswa kwemaitiro akasiyana uye maturusi. Aya maitiro ane chinangwa chekuona kunaka uye kushanda kweapp. Izvo zvakakosha kutevedzera kurongeka kwakakodzera kwezvishandiso izvi kuti uve nechokwadi chekubudirira kweapp. Kugadziridzwa kweAroid application kunoda ruzivo rwakakura kuitira kuti ibudirire. Akanyorwa pazasi mamwe eakanyanya kukosha maitiro anobatanidzwa mukuvandudza kweAroid application. Inotevera ingori mienzaniso mishomanana.

Iyo Android platform inoshandisa Google Tech Stack, inova chimiro chekusimudzira application kune nharembozha. Iyo dhizaini inosanganisira JetPack, Architecture Zvikamu, Room, LiveData, uye DataBinding, pamwe neJava uye State of the Art raibhurari seCoil neKotlin. Iyo yazvino yakagadzikana vhezheni yeJetpack Compose yakaburitswa muna Chikunguru 2021. Ichi chitsva chimiro chinopa mikana yekuvandudza yemuno mushandisi interface uye reactive programming modhi.

Iyo Android yekuvandudza maitiro inosanganisira akati wandei akakosha kufunga. Semuyenzaniso, iyo Android inoshanda sisitimu inoda app inoshanda zvisina musono nekamera yefoni uye bhatiri. Iyo app inofanirwa kuenderana nemidziyo yakasiyana, kusanganisira mapiritsi maPC uye mafoni. Pakupedzisira, iyo app inofanirwa kugadzirwa zvinoenderana nezvinodiwa nevashandisi. Haasi munhu wese anoda kugadzira Android app anofanirwa kunzwisisa maitiro anobatanidzwa mukukura kwayo.

Mutengo

Kana iwe uchitsvaga mugadziri wekuvandudza yako Android apps, iwe unogona kunge uchinetseka nezvemitengo yekuvandudza android. Sezvo Android-Kunden isingabhadhare mapurogiramu, mitengo yeAndroid-Entwicklung uye Maintenance yakakwira zvakanyanya kupfuura iyo yekutengesa app. Hezvino zvinhu zvishoma zvaunofanira kuziva nezve Android kuvandudza mutengo. Kana iwe uine app isiri kuita mari yakawanda, zvakanakisa kubudisira budiriro kukambani inoshanda mukusimudzira nhare.

Mari yekuvandudza App inoenderana nekuoma kweprojekiti yako. Kunyange zvisingaite kugadzira app yemahara, nzira yacho iri kure nekureruka uye inodhura. Zvizhinji zvemaitiro ekuvandudza zvinogona kuwedzera mutengo, kusanganisira ruzivo rwemushandisi, design, uye kushanda. Muzviitiko zvakawanda, zvinhu izvi zvinosanganisa kuwedzera mari. Sezvineiwo, unogona kuwana anochipa Android budiriro masevhisi muSwitzerland, zvakadai seSwiss Tomato. Iyo yakajairika Android app yekuvandudza purojekiti ichada 300-1,000 maawa ekushanda kubva kune mobile app developer.

Iyo yakanyanya kuvandudza yako app zano ndeye, zvishoma zvingangoita mari yakawanda kupfuura yaungatarisira. Zvisinei nekuti app yako yakaoma sei, iwe unofanirwa kurongera mutengo wekuenderera mberi kwevatengi mhinduro uye kugadzirisa. Ndinotenda, kune nzira dzakawanda dzekudzikisa yako Android budiriro mutengo. Heino sei. Usati wafunga kuburitsa yako mobile application yekuvandudza chirongwa, yeuka kuronga mutengo uye nguva yekuchengeta app yako. Iwe unogona zvakare kutsvaga emahara Android kusimudzira masevhisi.

Unogona here kuronga naKotlin?

Kana iwe wakamboshanda purojekiti uye waifanira kunyora chirongwa chayo, iwe unogona kunge uchinetseka kana iwe unogona kudzidza Kotlin. Iyo yakavhurika sosi programming mutauro iyo yemahara uye inowanikwa pasi peApache 2.0 rezinesi. Vagadziri vanoti zviri nyore kunyora Android application pane Java. Unogona kudzidza Kotlin nekuidzidza padivi peJava. Heano mamwe mabhenefiti ekudzidza Kotlin.

Chekutanga, Kotlin ane zvimwe zvinogumira. Mamwe marudzi e data anogona kuve asina maturo. Iwe unofanirwa kutaura zvakajeka yako Nullable Values. Izvi zvichakubatsira kudzivirira zvikanganiso zvine chekuita neNullPointerException. Zvisinei, haufanirwe kukanganwa kuti Kotlin ine yakakosha syntax yeNullable Values. Unogona kudzivirira nyaya idzi nekushandisa Safe Call Operator. Zvadaro, unogona kushandisa arrayOfNulls() basa. Izvi zvinobatsira kana iwe uchida kushandisa array ye null values.

Iwe unogona zvakare kushandisa Generics uye Zvinhu kuti uwedzere kutsanangura mashandiro echishandiso chako. Chero bedzi iwe uchitsanangura mabasa ako sebasa uye shandisa ma parameter akakodzera, unogona kuzvinyora setambo. Chimwe chinhu chinotonhorera ndeye Extension-Functions, izvo zvinokutendera kuti uwedzere kirasi pasina kugadzira makirasi matsva kana mainterface. Uye nekuti Kotlin inotsigira mabasa epamusoro, zviri nyore kunyora kodhi iri nyore kuverenga.

Wadii naKotlin?

Mubvunzo ndouyu, wadii kushandisa Java, panzvimbo yeKotlin? Java ndiyo yakakurumbira hurongwa mutauro ine yakapfuma ecosystem yeakavhurika-sosi maraibhurari uye maturusi. Zvisinei, ine zvipingamupinyi zvakawanda izvo Kotlin inoda kugadzirisa. Android Studio yakatogadzirirwa Java, asi naKotlin, inova yakagadzikana. Uye nyanzvi dzinotenda kuti Java neKotlin zvichavepo.

Chimwe chezvikonzero chikuru nei Kotlin iri nani pakuvandudza Android imhaka yekuti inotsigira Bytecode, kuibvumira kushanda kubva mukati meIDE yako, uye kana uri kutoshandisa Java, Kotlin inowirirana nayo. Imwe bhenefiti yeKotlin ndiyo yekuzvarwa null chengetedzo. Android inoshandisa null sechinhu chisina kutsanangurwa kukosha, izvo zvinogona kukonzera NullPointerException, kukanganisa kune ngozi kunogona kukanganisa app yese. Nekuva inbuilt null kuchengeteka, Kotlin anogadzirisa dambudziko iri, kubvisa kudiwa kwekuwedzera kodhi kudzivirira NullPointerExceptions kubva mukuparadza Android apps.

Chimwe chikonzero nei uchifanira kusarudza Kotlin pamusoro peJava yekuvandudza kwako Android hupenyu hwebhatiri hwakavandudzwa. Android O ichaunza nzira nyowani dzekuzivisa uye kupa vanogadzira kutonga kwakawanda pamusoro pemaapplication avo’ zviwanikwa. Zvisinei, ichave nemhedzisiro pahupenyu hwebhatiri. Saka, zvakakosha kufunga nezvese zvakanakira uye zvakashata usati wasarudza Kotlin pamusoro peJava. Kana ukangosarudza pane zvekupedzisira, inguva yekuhaya mugadziri akakodzera.
